Definitions
- My present invention relates to the production of substances that are optically transparent to infrared radiation and are usable in the manufacture of optical fibers or lasers and other radiation emitters.
- silicon-based fibers and other electronic components it is convenient to use the well-known chemical-vapor-deposition (CVD) process; see, for example, commonly owned U.S. Pat. Nos. 4,389,230 and 4,414,164.
- CVD chemical-vapor-deposition
- silicon can be obtained from one of the following reactions performed in a high-temperature furnace:
- Zinc sulfide and zinc selenide usable in fiber-optical technology for infrared transmissivity, are available in accordance with reactions
- the CVD process is designed to minimize the problems of radiation absorption, e.g. intrinsically by substrate/impurity bonds and extrinsically through scattering by the presence of anomalous domains. These latter may result from grain dislocations in a crystalline substrate or, with a vitreous substrate, from crystalline zones or from separation of phases of different densities.
- Redox reactions used in conventional CVD processes are sometimes accompanied by side reactions, involving different valence states, that give rise to undesired and often detrimental products.
- Reaction (4) may result in the formation of ZnH groups in the ZnS matrix, with the zinc in its monovalent form. These groups present absorption bands within the infrared range of interest lying between 2 and 12 ⁇ .
- the object of my present invention is to provide a modified CVD process which obviates the redox reactions yielding undesired compounds.
- the modified CVD process comprises vaporizing one or more chalcogen compounds and of one or more salts of a metal or metalloid, preferably a halide, and subjecting the resulting vapors under nonreducing and nonoxidizing conditions to a double-substitution reaction producing a chalcogenide (other than an oxide) of the metal or metalloid referred to.
- Chalcogens are members of the oxygen family in Group VIA of the Periodic Table, namely--besides oxygen--sulfur, selenium tellurium and polonium. I particularly contemplate the use of sulfur, selenium and tellurium for the practice of my present process in which I prefer their hydrides as a starting compound, i.e. H 2 S, H 2 Se or H 2 Te.
- the salt serving as a reactant is preferably a chloride of the metal or metalloid whose sulfide, selenide or telluride is to be produced.
- the double-substitution reaction eliminates the aforedescribed side reactions based on different valence states. It is particularly advantageous when the resulting chalcogenide is a high-boiling compound which during processing assumes a state of aggregation different from that of both the initial and residual reactants and byproducts, thereby facilitating the separation of the desired product.
- the desired product is solid at the processing temperature, which ought to be much higher than the boiling point of the reactants, the process requires low energy and, with equilibrium shifting entirely toward the right-hand side of the reaction, operates with an efficiency close to 100%.
- the metals and metalloids primarily usable in my process are arsenic, antimony, zinc, germanium, tin, lead, silicon and cadmium.
- the resulting chalcogenides, especially sulfides have a wide transmission window in the infrared range, with low absorption coefficients and a theoretical attenuation of about 10 -2 dB/Km at 5-6 ⁇ .
- Their thermal-expansion coefficient is 10 -6 /K which facilitates the drawing of optical fibers from glasses containing same.
- Their refractive indices of about 2 makes them suitable for the manufacture of glass/plastic fibers with a stepped index of refraction.
- FIGURE diagrammatically shows an installation for performing a modified CVD process as described above.
- two boiling vessels 1 and 2 respectively generate vapors of a chalcogen hydride and a metal halide. These vapors are concurrently led to a reaction chamber 3 heated to a start-up temperature which causes them to interact, in a nonoxidizing and nonreducing atmosphere, to produce a desired metal chalcogenide whose melting point lies well above the chamber temperature and which therefore precipitates as a solid at an outlet 4.
- the metal of course, could be replaced by a metalloid such as arsenic or silicon.
- Arsenic trisulfide is produced by a double-substitution reaction given by
- the hydrogen sulfide (or sulfur hydride) and the arsenic trichloride, respectively vaporized in vessels 1 and 2, have boiling points of about -60° C. and +63° C., respectively; chamber 3, to which their vapors are separately fed, is initially heated to about 200° C. to start up the reaction which is exothermic, generating a fusion temperature of around 300° C. This is still below the melting point of the arsenic trisulfide recovered as a precipitate at outlet 4. Reaction can be performed under atmospheric pressure.
- Mixtures of different solid chalcogenides can be obtained, as starting materials for glasses of predetermined composition, from combinations of metal or metalloid sulfides, selenides and tellurides treated in the manner described.
